c. CIFARMER VALVE LUBRICATING DEVICE Filed March 24., 1922 zmn al l y INVENTOR CLYDE C. FARMER BY M ATTORNEY CLYDE C. EARMER, F PETTSEBURGIJI, PENN EtYLVAN 1A, ASSIGEI 01-2, [t'l IE r 911 W'ILMEEDING, PEIJ'ITS ZL'VANIIA, A CURPGRATIG'Q HOUSE AIR BIRLAKE GCFMPANY, OF PENNSYLVANIA.

httih'iltl Application filed Ili'larch This invention relates to fluid compressors and has for its principal object to pro vide improved means for lubricating the reversing; valve of a fluid compressor.

'0 In the accompanying drawing, Fig. l a sectional view of the actual structure of the reversing valve portion oi a fluid compressor showing the improved means for lubricating the reversing valve applied thereto,

and Fig. 2 a digrammatic sec ional view of a portion of a compound fluid compressor showing the reversingvalve oi l sociated with the usual main steam distribution valve.

For the purposes of the present invention, it is not deemed necessary to show more than the reversing valve portion of the compressor, the compressor being of t e well known type as employed at the pre it time on locomotives for supplying); fluid under pressure for operating the fluid pressure brakes, the reversing valve portion being similar to that shown in Patent No. LNG,- 108 of Vi alter V. Turner, dated lvlarch 21,

shown in the drawing, the reversing valve portion of the compressor comprises a casino 1 having a valve chamber 2 contain ing the usual reversing; valve 3 for controlso ling pc is throupfii uhic-h steam is suppliwd to and exhausted from a main steam distribution valve, coi'uprising as shown in Fig.

: 6, connected piston heads 11, 19., 13, l and 15, the main valve being adapted to control admission and exhaust oi steam to and in the steam piston which operates the ju'i 'n'e ing piston, the exhaust of steam be- "ted by way of exhaust pipe The v. V is o 'icratcd l v a .alve rod which is moved up and down by the movement oi? the steam piston opposite ends of its stroke as in the Turner patent hereinbefore rel t'll'i'tltl to.

The reversing valve 3 is mounted to re ciprocate vertically and according to my invention, the port 5, which supplies .liv steam to the valve chamber 2 is disposed so as to enter the valve chamber tl' ough the valve seat 6 at a point above the reversing valve 3, the port 5 leading to a steam supply chamber 7 preferably of relatively large capacity, the chamber *5 being connected to the steam supply passage 17. In the usual well known manner, lubricating oil is fed 1822. Serial No. 548,528.

on the walls of the chamber 7 and win in icient quantity, the oil will flow out through the port 5 and into the valve chamber 2 and will then trickle down the valve thus providing the desired lubricathe reversing valve.

may be stated that oithculty has been periennd in man cases due to QXCGS r of the i e it of the reversir v.1

wing to lack of SJilidQllb lubrication and vhile a separate lubricator might be pro ied for lubricating the reversing valve,

would involve additional er; ense as as care and maintenance, which is voided by my improvement. 7

sing now described my invention, what I claim as new and desire to secure hv letters Patent, is

1.. A valve chamber, a steam controlliarjg valve in said chamber, a vertical valve seat upon which said valve operates, a chamber supplied with steam carrying lubricating oil, and passage leading trom said suppl chamber and opening to the valve sea point above said valve sothat luh i ii from the steam, collecting on the 1 iv chamber will flow ti rou down the ersing valve portio 7d compr or c.

a valve chamber i re seat in said sham e operating on f tor the of steam from said 0' steam suj Jr W icaung; ull l easing, item v Llld valve sea :1 supply 0 ssage and onto sa valve. 305
